The small black eyes were fixed on him, unblinking, and he saw the tip of Caswell’s tongue steal out, barely visible, to lick away a drop of wine from the corner of his mouth.

Sweet Jesus. He sat dumbstruck for an instant, caught in those eyes, then glanced down, as though suddenly remembering his own wine. He lifted his glass, lowering his lashes to hide his eyes.

In defense of King, country, and family, he would unhesitatingly have sacrificed his virtue to Nessie, had that been required. If it was a question of Olivia marrying a man with syphilis and half the British army being exterminated in battle, versus himself experiencing a “personal interview” with Richard Caswell, though, he rather thought Olivia and the King had best look to their own devices.

He put down his glass, hoping that this conclusion was not reflected upon his features.

“I have something other than money,” he said, meeting Caswell’s gaze squarely. “Do you want to know how George Everett really died?”

If there was a flicker of disappointment in those black marble orbs, it was swamped at once beneath a wave of interest. Caswell tried to hide it, but there was no disguising the glint of curiosity, mixed with avarice.

“I heard that it was a hunting accident; broke his neck out in the country. Where was it? Wyvern?”

“Francis Dashwood’s place—Medmenham Abbey. It wasn’t his neck, and it was no accident. He was killed on purpose—a sword-thrust through the heart. I was there.”

These last three words were dropped like pebbles into a lake; he could feel their impact send ripples through the air of the room. Caswell sat immobile, scarcely breathing, contemplating the possibilities.

“Dashwood,” he whispered at last. “The Hellfire Club?”

Grey nodded. “I can tell you who was there—and everything that happened that night at Medmenham. Everything.”

Caswell fairly quivered with excitement, black eyes moist.

George had been right. Caswell was one of those who loved secrets, who hoarded information, who kept confidential information for the sheer joy of knowing things that no one else knew. And when the time might come that such things could be sold for a profit . . .

“Have we a bargain, Dickie?”

That recalled Caswell somewhat to himself. He took a deep breath, coughed twice, and nodded, pushing back his chair.

“That we have, my little love. Come along, then.”

The upper floors consisted mostly of private rooms; Grey couldn’t tell whether much had been changed—he had been in no condition to notice very much on the occasions of his previous visits to Lavender House.

Tonight was different; he noticed everything.
